Subject: [IBIS] Ibis generation problem

Hi,
I'm having problem generating an ibis file, and was wondering
if I can get ideas in how to approach this.
1) The problem:
I get the following error when running spice to ibis:
% s2ibis2.11 gold_7xxx.s2i
s2ibis2.11_real v1.1 -- North Carolina State University
s2ibis2.11_real: Reading input file gold_7xxx..done
s2ibis2.11_real: Analyzing component idt7xxx .
s2ibis2.11_real: Starting HSpice job with input put7.spi.
:
etc
:
s2ibis2.11_real: Starting HSpice job with input y017.spi.
s2ibis2.11_real: Starting HSpice job with input z017.spi.
s2ibis2.11_real: Opening file gold_7xxx.ibs for writing...Bus error
-----
2) My attempt at solving this:
And so I examine the gold_7xxx .ibs file, and I see the following:
:
etc
:
[Pulldown]
| voltage I(typ) I(min) I(max)
|
-3.30 -9.001A -9.160A -8.914A
-3.10 -8.255A -8.415A -8.168A
:
etc
:
3.50 0.178A 0.117A 0.241A
3.60 0.179A 0.117A 0.242A
3.70 0.179A
(The ibis file ends here, which is far from being complete.)
I have examined all the *out files (especially the pdt.out, pdx.out,
pdn.out files)
in detail and see that all hspice data has been generated and dumped
into the
*out files with no problem whatsoever. And yet s2ibis is apparently
having
problem extracting the data from the *out files to place in the *ibs
file.
Any idea how to approach or solve this problem?
Has anyone ever encountered this?
Any help or hints would be appreciated. Thanks so much,
- Wil
